I'm Dr. Lindsey Doe, clinical sexologist and host of this sex-curious show, Sexplanations. Today's episode is sponsored by Unbound, who sent me some very sexy jewelry.

[intro]

For thousands of years, human beings have been adorning themselves with metal, bone, stones, and the like -- what we call jewelry. This Greek fresco shows a woman with large hoop earrings from circa 1650 before common era (BCE). This painting depicts ancient Egyptians wearing earrings, necklaces, and bracelets. Jewelry, for millennia, has been a way to mark wealth, accentuate beauty, and protect us.

And some jewelry has a sexual or romantic purpose. Poison, or pillbox, rings have been around for at least 2000 years to hold a loved one's portrait, lock of hair, or cologne (or to slip lethal powder into a cheating lover's drink). Pendants like this one from ancient Rome or India are explicitly a phallus, a penis shape. Those from Rome are called fascinum or fascinus, named after the deity of the same name. Baby boys were given these protective pendants 9 days after birth to ward off evil as children and combat the jealousy of other men as adults. In India, they're called palad khiks and they're also considered protective against murder, rape, and theft.

Another way that jewelry has taken on a sexual connotation is through these modern designs by Unbound. I chose five pieces from their collection to show you, but there are many, many more available on their website. This is the Amelia Whip Choker, named after Amelia Earhart because she was a risk-taker who pursued adventure. She was also keen on open marriage. In a letter to her fiance, Earhart wrote, "On our life together I want you to understand I shall not hold you to any medieval code of faithfulness to me nor shall I consider myself bound to you similarly," and continues with an expectation that her spouse-to-be will let her go in a year if they don't find happiness together. I'm into that sexual meaning of this necklace, but there's another and another.

It's a choker and thin black or red chokers are thought to have been accessories of sex workers in the 1800s. Black or woven ribbon chokers in the early 1900s was a way to signal that you were a lesbian. And, even today, a sturdier leathery or chain choker indicates submission to sexual domination, like a collar your master can put a leash on, which relates to its third sexual connection. If I unclasp it, my choker becomes a whip for light BDSM. Hey, partner, up for a little masochism or pleasure from pain. Small silver handle and three leather falls, what you would call individual strands of a flogger or whip. The falls are looped without crackers at the end that might break the skin or make a loud noise, so it's mild and not likely to intimidate anyone.

My other necklace is the Amelia Lube Vial Necklace, a stainless steel capsule that looks chic and holds lube. We can pour a little coconut oil in there, and it's body friendly and smells good. Just remember, oil-based lubes cannot be used with latex products, like gloves and condoms, because oil deteriorates latex.

Now for my bangles of bondage. I can slide these easily on and off of my wrist, but if you need to, you can unclasp the chain from the bangle, open it, slide it onto a person's wrist or a bedpost, then reclasp it.

My ring: Twiggy Massage Ring. This one is from a separate collection named after model and actress Lesley Lawson, also known as Twiggy. She's an androgynous icon from the 1960s Free Love movement. Unlike her peers who dressed ultra-femme and wore up-dos, Twiggy kept her hair short and her look gender-undifferentiated. The Twiggy ring can work out knots in your shoulders, or if you reverse it and put it on like this on your fingertips, it cna give a unique touch sensation to the vulva.

Can you guess where the last piece of jewelry I'm wearing is? Twiggy Nipple Clamp Earrings. Besides being erogenous tissues, the nipples and earlobes are non-gendered body parts, and earrings or nipple decor are considered unisex jewelry. What I love about these cute gold pineapples is the ability to wear your sexuality in plain sight if you want to. And be able to carry sex toys on your body so you have them wherever you go, like the lube on my neck and the bondage on my wrist.
